Analysis Of Stability Of Shuangli Mining Of Open-pit Slope Based On FLAC3D

The Shuangli iron deposit is a medium-sized iron ore field, The No.2pit of Shuangli’sminingthickness orebody is relatively large, And his relatively shallow burial depth,ore gradeis high,The covering of miningthickness orebody on the surface of the ore body is thin,suitablefor Open-pit mining. Development and construction of this project not only makes the localresource advantages into economicadvantages, but alsomade a big contribution to the localeconomic development.In open pit mining, The prediction problem of slope stability is a main problem inMiningEngineering Research of open pit mine slope,It also is the most difficult and the most urgentproblem in our open-pit research. Through the research on the stability in open-pit slope andforecast of theunstable region,We can future on the slope of open pit mining in referenceforreinforcement and monitoring.In all kinds of slope parameters of open-pit mine, the final slope is an important part ofopen-pit mining is to mine angle optimization, which is stable and open pit mine safetyproduction. The slope parameter selection is scientific andreasonable, it will not only be stableand safe production guarantee of open-pit slope, and it will also benefit to the recycling ofresources and enterprise will have the effect of major. The use of FLAC3D modeling andanalysis of open pit mine slope, the numerical simulation model to determine open-pitslope whoregion relative to other regions is more prone to landslidephenomenon of ultimate slopeopen-pit slope angle and rational analysis,namely the unstable region.So the determination of slope angle with the determination of slope angle with the doublemine expansion and slope stability based on the project, the purpose of the study is to determinethereasonable stope final slope angle, as well as regional analysis of open pit slope damage,provide reference for the later monitoring. Using the FLAC3D numerical simulation analysis ofthe open pit slope stability simulation software,to forecast landslide place, avoid the rock slopeof open-pit mine landslidecause serious safety accidents. Our specific research mainly includesthe following two aspects: the analysis of open pit slope stability problem After slope expansion,find out the open pit slope stability is relatively poor areas; law and trend of slope displacementanalysis of open-pit mine. The Shuangli mining expansion side slope stability research significance is: to ensuresustained and stable production of mining safety and miningconditions, the final slope ofopen-pit slope angle as large as possible, one can improve the recovery rate of ore mining,reduce the waste of resourcesand improve economic efficiency; on the other hand can guaranteemine safety, sustainable and stable development.
